Title: Magnetic bubble logic array
IPC: H03K19/168
Filed: 1975-05-21
Abstract: 1488727 Magnetic bubble logic circuits INTERNATIONAL BUSINESS MACHINES CORP 21 May 1975 [15 July 1974] 21709/75 Heading H3B A magnetic bubble logic array capable of producing at an output 107 different logical combinations of input data x, y comprises a decoder 15 producing different logical combinations at outputs 153-156 and means 26 connected to each decoder output and under the control of bubbles on paths 103-106 to select the required logical combination for passage to the output 107. As shown, the decoder 15 includes generators 20 producing "one" inputs to one set of gates 21 which in the horizontal direction have an EXCL-OR function and in the downward direction have an AND function. The outputs xy, xy, xy and xy therefore appear at outputs 153-156 and one of these is selected by the presence of a control bubble on the appropriate path 103-106 from a register, bubble generator or bubble gating control switch propagating over crosspoints 25 to an AND gate 26 to divert the output over OR gate 17. The gates 21 comprise a T and I bar pattern (Fig. 2B, not shown) having two bubble inputs (A, B) such that either alone propagates under a rotating field to an EXCL-OR output whereas both together mutually repel at an intermediate location to produce an AND output whilst the other bubble is diverted to an annihilator. Similarly, a T and I bar pattern (Fig. 3B, not shown) performing the function of AND gates 26 operates so that either input (A, B) alone proceeds to an annihilator whilst both together causes mutual repulsion at an intermediate point to divert one bubble to the annihilator and the other to the AND output. The OR-gate 17 consists of a chevron pattern (Fig. 4, not shown). The logical combination may automatically be altered according to the input data.

Title: Method for accelerating the growth of micro-organisms
IPC: C12N13/00
Filed: 1961-06-20
Abstract: The reproduction of Penicillium notatum and consequently the production of penicillin is accelerated by suspending P. notatum in an aqueous solution containing lactose, corn steep liquor, glucose, NaNO3, KH2PO4 and MgSO4 and subjecting the culture to cavitation by means of sonic energy at 20 kilocycles per second at a level of 2.2 watts per c.c. of the mixture and temperature of 70 DEG F.-75 DEG F. for 20 hours and thereafter at 2,5 watts per c.c. for 10 hours. Ergosterol is produced in increased yield by suspending Saccharomyces cerevisae in an aqueous solution containing glucose, beef extract and sodium chloride and subjecting the culture to cavitation by means of sonic energy at 21 kilocycles per second with a power input of 4,5 watts per square inch of surface radiating the sonic energy for five hours at 85 DEG F.ALSO:The reproduction of micro-organisms is accelerated by incorporating the organisms in a liquid nutrient medium to form a culture liquid and subjecting the culture liquid to sonic energy at a frequency below 50 kilocycles per second and at a power level sufficient to effect cavitation of the culture liquid but insufficient to disrupt the cell structure of the micro-organisms. The temperature of the culture liquid is maintained substantially at a level most favourable to the growth and reproduction of the micro-organisms and the power level of sonic energy is increased after the number of micro-organisms in the culture liquid has substantially increased.  The examples relate to the reproduction of (a) Penicillium notatum using sonic energy at 20 kilocycles per second at a level of 2.2 watts per c.c. of mixture for 20 hours and then 2.5 watts per c.c. for 10 hours at a temperature of 70-75 DEG F.; (b) Acetobacter suboxydans as in (a); (c) Saccharomyces cerevis using sonic energy at 21 kilocycles per second with a power input of 4.5 watts per square inch and a temperature of 85 DEG  F. to give increased production of ergosterol; and (d) Anacystis nidulans using sonic energy of 21 kilocycles per second with a power input of 4.5 watts per square inch of surface radiating the sonic energy and a temperature of 100 DEG  F.
